CORN-SH ELLER.

SPECIFICATION frming part of Letters Patent No. 252,373, dated Janlary 17, 1882 I' Application filed May 26,1881. '(No model.) 4

To all whom t Vmay concern:

Be it known that I, HIRAM A. HAWKINS, of Chicago, in the county of (look and State of Illinois, have invented a new and useful Corn- Sheller, of which the following is a specification.

My invention relates to improvements in corn shellers in which are cylinders and cases made in sections or staves, and automatically adjustable; and the objects of my invention are, first, to provide a cylinder and case both made in staves or sections, the sections or staves being removable; second, tolfurnish an attachment or spring, in connection with the cylinder and case, so that they will automatically adjust themselves; and, third, to furnishA a corn-Sheller which will require less power than those now in use, and be cheap, light, ,j and durable.

I attain these objects by'the mechanism as illustrated in the accompanying drawings, in .which- I Figure l is a side view of my new cornsheller. Fig; 2 is a sectional view on the line x x of Fig. 1. Fig. 3 is atop view of the bottom plate upon which rest the case and cylinder, showing their plate connections, and with each other. Fig. 4L is the inside of one of the staves or sections of the case, showing position of teeth. Fig. 5 is-an edge view of the same. Fig. 6 is an outside view of one of the staves or sections of cylinder, showing position of teeth and shape of edges forming the openingsbetween the staves for thcdischarge of the shelled corn. Fig. 7 is an edge View of the same. Fig. 8 is a bottom view of the top of the cylinder, showing the sockets for the reception ofthe ends of the staves, and showing groove. Fig. 9 is a view showing the spring attachment `for automatically adjusting the staves of the case.

Similar letters refer to similar parts throughout the several views.

A is a case of a corn-Sheller. It is made of staves or sections a a, the staves being rc- Inovable. The tops of the staves a a rest in a. groove in the lower edge of hopper B, and the bottoms of staves on projection F, as shown in Fig. 9. j

Bis an ordinary hopper, provided with a groove for reception of top ot' staves a a,.-

C is a cylinder, made ot' removable staves or sections b b.

a ct are staves forming case A, and are made in the shape as shown in Figs. 4 and 5. They are provided with teeth or projections h h, which teeth are in tlje position as shown, having projection V.

b b are staves forming the cylinder' C, and made in theshape as shown in Fig. 61, so that holes w will be in the cylinder forthe passage of thecorn. b b have teeth c on the outside I for separating the corn from the cob. Thetop ends ofb b rest in sockets c eof head of cylinder, the bottom end resting in a groove on spider W. I i

D is the head of the cylinder. It is keyed upon the shaft K. It is hollowed out upon its under side, and has a groove, d, with sockets e, for reception of the end of staves b b.

E is a plate, made of iron, having projections Fand n, and serves as a support for the cylinder and case..

F is a projection on the upper face of E, having head or shank f, all cast in one piece, and also solidly cast with plateE. F is cast in shape as shown in Fig. 9. fhas a threaded hole, i", through which the tension-screw R passes.

R is a tension-screw.

T is a washer, loosely attached t-o end of R, and having shank t for spring S, all as shown in Fig. 9.

S is a spring, and is for the purpose of allowingthe staves to automatically adjust themselves. At one end it has a bearing on t, and at the other on projection V of stave a. Each stave a has thearran gement as shown in Fi g.9.

H is an iron frame for the support of the corn-Sheller. V

K is a revolving shaft passing through the center of the cylinder C. Its top end passes through bearings in frame H, and has a pulley attached, and its lower end rests in a centerlift trampot supported bylever M, the lever M being supported by rods N N, running up through plate E and having hand-wheels P.

Underneath the hand-wheels P are coiled springs g, which have a bearing on plate E and Wheel P, as shown in Fig. 1, and are for the purpose of automatically adjusting the cylinder. l

L is an iron bridge-tree or shaft-support.

W is an iron spider, having grooves to receive lower end of staves b b, and is held in position by rods 7c 7c.

k k are iron rods, which pass through the Spider W and cylinder-head D, as shown vin Fig. 2, heing secured at both ends by nuts.

These rods 7c k keep spider W and staves b b in position, and by slacking the nuts the sta-ves may be removed when desired. v

n a are projections on E for separating the ends of staves a a and preventing the staves passing inwardly or sidewise, they being made inclined, with a hook, as shown in Fig. 9, and are cast with E. Y

w a: are holes in the cylinder, which are formed when the staves bl) are pnt together and the cylinder com plete, and are for the purpose of a discharge of shelled corn through the spider W.

All the several parts ot1 my invention are made of iron; 4but they may be made of any material suitable for the-purpose, and are arranged as shown.

The manner of operation is as follows: The machine is put in motion by power attached to shaft K, causing the shaft and cylinder to revolve.

The corn is pnt into the 'hopper B, l

and it passes down into the machine between the cylinder C and the case A and between the teeth c and h, and the corn will be forced from the cob. vThe separated corn will pass down into a reservoir for the reception of the same. Some of the corn will pass through the holes w and spider W into the reservoir,the holesw acting as a relief for the general delivery. In the eventa large cob passes down, the staves of the case will adjust themselves so as to accom modate a large or small cob, automatically moving forward or backward; and in the case of a very' heavy strain the cylinder will yield downwardly, thereby enlarging the general delivery, obviatin g the danger of breaking 5 and, if desired, the cylinder and case may be separated into their several parts or sections in a few moments.

What 1 claim as new and original, and desire to secure by Letters Patent, is-

1. 4The combination, in a corn-Sheller, of thc Vplate E, having projections F and n, with the case A and rods N,'subst`antially as described and shown. 'g

2. The combination, in a corn-Sheller, of the hopper B, cylinderC, case A, grooved spider W, and plate E, having projections F and n, the `said case and cylinder bein g formed in sections and provided with devices for rendering them automatically adjustable, substantially as shown and described.
